Bernard Friedman was appointed in 1988 by President Ronald Reagan. The 70-year-old Friedman was a District Court judge in Oakland County before getting a big promotion to federal court in Detroit.

Friedman was the court’s chief judge for 4 ½ years until 2009.

On Friday, Friedman released his 31-page ruling exactly two weeks after a rare trial that mostly focused on the impact of same-sex parenting on children. The challenge was brought by two Detroit-area nurses originally seeking to overturn Michigan’s ban on joint adoptions by gay couples.

The judge noted that supporters of same-sex marriage believe the Michigan ban was at least partly the result of animosity toward gays and lesbians.
